(alien-#327) "This invention relates to a dispensing device forcalking material and the like, comprising a handle in which one end of acartridge'adapted to contain such material maybe mounted, the handlecarrying meanstc engage the far'end of the "cartridge and hold it inplace and being equipped with manually operable feeding mech- 'a;nism toexpel the contents from the cartridge.

'Ihe'objectof the invention is to provide an extremely simple device for securing the cartridge place, enabling the expulsion of the contents as desired by manipulation of a suitable hand "lever on the handle.

In' its preferred form my invention employs a cartridge in the form of a paper tube having 'at'one'end' an internal cap which may act asa plunger in extruding material, and at the other end a cap having a central opening "through which the extrusion takes place. A spout is carried by the dispensing apparatus and in use registers with the discharge opening.

strip, the cartridge with its two caps forms a ready. shipping container for the calking material.

""Whenit'is desired to usethe cartridge, it is only necessary to mount it in the apparatus,

which is equipped with means to engage and position the rear end of the "cartridge while the forward end engages the device carrying the and suitable pawls adapted to advance the rod and retain the gain made. Such pusher acts to advance the internal cap as a plunger to force the material forward,

breaking the frangible seal and discharging through the spout.

A'preferred form of the'invention isillustrated 'in' the drawings hereof and is hereinafter more fully described and the essential novel features are set out 'in the claims.

In the drawings, Fig. l is a longitudinal section of the complete dispensing device showing the cartridge mounted in position in the apparatus; Fig. 2 is a fragmentary longitudinal section through 'thepositioned cartridge at thedischarge end; Fig. 3 is a plan of the apparatus showing the parts in the act of positioning the cartridge; Fig. 4 is a cross section through the mounted cartridge indicated by the line 44 on Fig. 1; Fig. 5 is a cross section through the hand grip, as indicated by the line 5--5 on Fig. 3; Fig. 6 is a detail in cross section, as indicated by the line 6-4 on Fig. 5; Fig. 7 is a modified cross section in a plane indicated by the line 5-5.

As shownin Figs. 1, 2 and 3, 10 indicates the body of a cartridge which is preferably a'paper II indicates an When the discharge opening is closed'by a suitable frangible fspout. The discharge apparatus may comprise a pusher rod, hand lever to receive that end of the cartridge andhaving a central opening adapted to'register with the discharge opening'of the cartridge. The connection at either the inner or outerend of the rods is "rod 50 having a disc 5| on its forward end-which discharge. a

The dispensing I or handle 20 preferablymade of sheet material doubled forwardly on itself and formed into a hand grip'which atthe forward end has a trans- "verse channel member 2! abutting and secured to "by the" pusher of the apparatus to discharge the ccntents. "Such cap, which may if desired" be a' sheet metal disc having a flange, is indicated near the discharge position at H in Fig. 1. l2 indicates the external cap at the discharge end as shown in Fig. 2; This external cap has a double flanged-edge It whichembraces thewall ofthe cartridge and at the center has a dischargeopen ing l4. When the cartridge is shipped this opening is closedby a thin frangible seal is secured to the inner face of the cap.

When the cartridgeis mounted and theplunger at the other end actuated the pressure breaksthe seal r5, so that the contentsmay be discharged through'the opening M, andthence 'throug'ha suitable spout carriedbythe apparatus. The cartridge with-its two capsaccordingly constitutes the shipping container and immediately upon receipt bythe user, it may be placed'in the dispensing apparatus of this invention for apparatus comprises a body a disc22. This-disc is provided atits edgewith a flange 23 which extends cylindrically for half a circumference, the terminal diameter being "preferably in a vertical plane. Such half-sleeve "23 and the disc '22fiaccordingly form a the rear end of the cartridge.

seat for A pair of rods 3iilying in a vertical plane'are connected at their'rear ends to the handle'and at their forwardend to a cap ii! of suflicient size pivotal so that the cap may take aposition at an angle to the head of the handle. It is preferable topivot the cap to the ends of the'rods and this cap preferably" carries a spout ii. If "desired; the spout may be removable and internally fthreaded on an external thread'cf a short tube llsecured to the cap.

In mountingthe cartridge theiar end merely "placedin the cap ll) which is swung so'mewhat'to one side as indicated in Fig. 3, and'thenthe cartIidgdis swung in the opposite direction across "the front plate 22 intoengagernent witlr'the "semi-cylindrical sleeve 23. In this position the cartridge may be readily retained by the 'first "jfinge'r of the operator extending along ide of the open side ofthe retainer "23 and the adjacent portion of the cartridge, until the pusher-mechanism, about to be described, enters the cartridge,

after which the pusher" plate on such mechanism retains that end of the cartridge in position.

The dischargingapparatus includes a pusher A hand lever 52, pivoted to thegrip 20, oper-. ates suitable mechanism to advance the rod '50. As shown, the mechanism comprises a pair '0! washers 53 normally loose about the rod. and pressed in idle position by a spring 54 operating against an abutment 55 in the handgrip. When the hand lever is drawn by the operators fingers into the grip the upperi end of the lever forces forwardly the lower portions of the washers skewing them and causing them to bind against the rod 50 and feed the same forwardly. The gain is retained by a detent pawl 56 normally pressed by a spring 5! into position to bind against the rod. As the rod is fed forwardly,

however, it carries the detent pawl into a more nearly vertical position and passes freely through it. At the end of the stroke, the spring 51 returns the detent pawl to the inclined position where it bitesinto the rod and prevents retraction thereof and accordingly maintains the gain made by the actuation of the lever 52.

, At the end of the operation of discharging the contents of the cartridge, the disc 5| on the end of the rod 50 has shoved the cap .ll practically to the opposite end of the cartridge and against the interior of the cap I2.

When it is desired to withdraw the rod the operator actuates an L-shaped lever 58 shown in idle position in Fig. 1 K and turns it upwardly into the position shown in Fig. 3. In this position the short arm of the lever engages the detent pawl 55 and cams it to 'idle position, thus allowing the rod to be freely withdrawn. When completely withdrawn, the cartridge is free to be swung laterally as indi-" cated, for instance, in Fig. 3 and then withdrawn from the cap 40 and discarded.

Thetwo rods 30 may be in the form of a bail having an intermediate portion 31 In Figs. 5 and 6, I have indicated a pivotal connection between the bail and handle effected by loops on the channel member 20 overhanging extending through the handle and suitably secured thereto.

the bail. In Fig. 7 the bail is fixed to the handle, H I

which may be readily effected by an ear 26 on the handle overlapping a laterally looped portion .32 of the bail. At the far end, the two arms 30 of the bail are preferably pivoted to the cap 40 by cars on the latter embracing loops 33 on the usual manner of a calking gun. The cartridge may remain in the apparatus as part of the com-" plete gun until the material has been entirely used; thereafter merely withdrawing the pusher rod and swinging the cartridge to one side frees it from the apparatus, enabling the installation of a fresh cartridge.
